Hello, I am working on a virus capsid and trying to figure out the buried surface area between subunits (similar to what ViperDB has. I have to do this for a few capsids and I am trying to automate this to the maximum possible extent. I have been able to follow the steps in this link Buried surface area calculation <http://www.cgl.ucsf.edu/pipermail/chimera-users/2006-December/001131.html> and manually calculate the information. Are there commands available to do the same? Also, what is the difference between the surfaces created using a multiscale model and surfaces computed from the atom-spec? Would this difference in the surface affect the calculation of the buried surface area? And if it does affect it which one be a more accurate representation? Thank you Vamsee
